Ancient Device

The Ancient Device is not an event, but it contains so many variations of content similar enough to an event to be considered for the category. Much like an event, the Ancient Device often houses a dungeon, and there's also an achievement called Wheel of Misfortune for fulfilling every possible variation that the device can offer.

There are ten different outcomes that the device has to offer, from a treasure chest to a dungeon with a killer chicken, and they are chosen at random, roulette-style.

The below possible outcomes of using the ancient device are not listed in any particular order. By appearances and testing, it's possible that they all have the same probability to spawn. Since the achievement tracks 10 unique outcomes, some of the following may not be counted, or may have existed only in the past.

1. The Veiled Treasure - a small dungeon with numerous Resplendent Chests inside will spawn, complete with elite packs. There is also a high probability of a Treasure Goblin spawning, as well.

2. The Fowl Lair - This dungeon contains an enemy that is most horrendous and revolting. With grease.

As soon as you land, head left to the exit from the Archives into the Desolate Sands. You will get a Checkpoint as you near the exit.

Head right over the bridge and into the sands. A short way in is the first location the Ancient Device can spawn (1). Look for steps up to the device.

If none are there Teleport to town and take the Waypoint to the Ancient Path.

A short way from the end of the path into the Sands is the second possible spawn point (2). Look for steps up to the device.

Special Notes:

If the Ancient Device does not spawn in either location leave game and resume. Head down the portal from the Hidden Camp directly to the exit from the Archives of Zoltun Kulle and start the hunt again.

It can also be done in Adventure Mode, except that the Ancient Path Waypoint will not be available.

However, there is a bounty called "Bounty: The Ancient Devices." If you happen to get it, you will be able to activate four devices in one game.
